In blade groove on wheel disc, blade passes through blade groove.Between impeller sleeve and the retaining ring of transmission shaft axis body, spring is installed.It is living
Movable vane wheel is close to the impeller disk under spring force effect.Combined impeller rotation, active impeller is under the pressure effect of conveying liquid
It is displaced, the blade protrusion height in impeller disk blade groove is decreased or increased.Combined impeller changes feed flow according to pressure change,
Realize lift automatic adjustment.
The present invention is further improved, the optimization technique measure taken is: several pressure ports are provided on the impeller disk.
The present invention is further improved, the optimization technique measure taken is: on the efferent duct of the pump housing, control being installed
Valve；The control valve is closed, and dredge pump internal pressure increases, the blade in impeller disk blade groove, retreats retraction blade under pressure
In slot, the dirt being stuck on blade wall surface falls off.
Beneficial effect
Based on above technical scheme, the utility model at least has the advantages that one of them:
1, the active impeller of combined impeller acts on bottom offset in the pressure of conveying liquid, and the blade in impeller disk blade groove is stretched
It is highly decreased or increased out；Combined impeller changes feed flow according to pressure change, realizes lift automatic adjustment, structure is simple,
It is practical, it is easy to repair；
2, dredge pump internal pressure is increased, the blade in impeller disk blade groove retreats in retraction blade groove, card under pressure
Dirt on blade wall surface falls off, and realizes the work of impeller automated cleaning.
